COTTON SEED-DELINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 614,435, dated November 22, 1898.

Application filed January 27,1897. Serial No. 620,917. (No model.)

'delinting-cylinder made up of a plurality of block-holding wheels arranged side by side and carrying abrading-blocks which cooperate with the abrasive lining of the casing. In the improvement of delinting-machines of this class the present invention has for one of its objects the provision of a novel form of block-holding wheel having means for rigidly clamping the emery or abrading blocks, so that liability of loosening is entirely obviated, While at the same time securing the blocks in position in such a manner as to leave no projeoting edges that would assist in unseating or tearing the blocks from their proper positions, and in the accomplishment of this very desirable object the blocks are secured by the several wheels comprising the cylinder in such a manner that the entire exterior or peripheral area of the delinting-cylinder presents an abrasive surface and no metal or other parts of thecylinder are exposed that are not entirely covered by the emery-blocks. This result is of especial importance in delinting-machines of the class referred to, inasmuch as in some machines of this character metal parts have been exposed to the friction of the cotton-seed and become heated to a sufficient degree so as to cause material expansion and a consequent liability of cracking or displacing the emery-blocks. In short, the present invention contemplates the formation of a delinting-oylinder of the sectional type having a substantially solid periphery of emery throughout its entire exterior area, which solid periphery of emery is made up of a plurality of segmental emery-blocks lying in the same cylindrical plane and each of which is securely fastened throughout its entire length in the particular wheel-section of the cylinder carrying the same.

With these and other obj eots in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is avertical sectional view of a ootton-seed-delinting machine, illustrating the improvements contemplated by the present invention and showing in dotted lines the usual air-flume. Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a side View, partly in section, of one of the block-holding wheels or wheel-sections of the cylinder. Fig. 4 is a vertical sectional view of the block-holding wheel. Fig. 5 is a detail sectional view of one of the side plates or disks of the wheel. Fig. 6 is a detail in perspective of one of the seg= mental emery-blocks.

Referring to the accompanying drawings, the numeral 1 designates the machine frame or stand supporting a cylindrical casing 2 and provided with the usual feed and discharge openings, the feed opening 3 being illustrated in Fig. 1 of the drawings and arranged in a line with the usual feed-pipe 4r, fitted to the upper side of the casing at the head end thereof and serving to direct the seed to be delinted within the casing. The cylindrical machine-casing 2 has fitted to the inner surface thereof the usual abrasive lining 5, preferably formed of emery-blocks suitably fitted in place, and this inner abrasive lining 5 of the machine-casing 2 cooperates with the revolving abrasive surface of the revolving delinting-cylinder 6 to provide the necessary scouring or abradin g action for loosening the lint fiber from the seed, which is confined and worked within the comparatively small space between the abrasive surface of the cylinder and the abrasive lining of the casing.

The revolving delinting-cylinder 6 is of a length equaling that of the horizontal cylindrical casing 2, and in the present invention comprises a plurality of circular block-holding wheels 7 arranged side by side on a common cylinder-shaft 8, extended through opposite ends of the cylindrical casing 2 and journaled in suitable bearings 9 on the machine frame or stand 1, motion being. communicated to the said shaft 8 in the usual way. Each bloclcholding wheel 7 essentially comprises a pair of oppositely located parallel side plates or disks 10, one of which side plates or disks 10 is formed at its center with a laterally-extending hub-sleeve 11, reduced at one extremity, as at 12, to snugly register in the central circular hub-opening 13 of the opposite plate or disk 10. When the oppositelylocated side plates or disks 10 are assembled with one of said plates or disks fitted on the reduced extremity 12 of the hub-sleeve of the opposite plate or disk, the same are securely fastened together by means of a plurality of tie-bolts 14, arranged, preferably, in a circle concentric with the hub 11 and secured at their ends in perforations or openings formed in the said plate.

At their inner peripheral edges the oppositely located detachably connected side plates or disks 10 are chamfered, as at 15, and at the inner edge of the bevel are formed at their inner sides with the annular shoulders 16, on which shoulders rest the opposite edges of a base-ring 17, lying in the space between the chamfered peripheral edges of the side plates or disks and firmly clamped in position by the bolts 14. The base-ring 17, in connection with the inner chamfered peripheral edges 15 of the side plates or disks of the wheel, forms around the periphery of the latter a dovetailed seat for snugly receiving therein the wide dovetailed tongues 18, projected from the inner sides of the segmental emery abrading blocks 19, which are arranged on the wheel in a circular series and in the same circular plane.

While the base-ring 17 and the peripheral edges 15 of the side plates 10 form a seat for receiving the dovetailed tongues of the abrading-blocks,it is to be observed that the said side plates and their peripheral edges 15 provide lateral clamping means for engaging with the side edges of the abrading-blocks. It is important that each of the block-holding wheels should be provided with lateral clamping means for engaging the side edges of the abrading-blocks in order that the said edges of the abrading-blocks may overhang or overlap the peripheral edges of the wheel and lie flush with the side faces of the latter for the purpose hereinafter fully explained.

The number of segmental abrading-blocks 19 fitted to each wheel will depend largely, of course, upon the size of the wheel; but it will be understood that by reason of having a pl urality of the segmental abrading-blocks on each wheel of the cylinder each block is separate] y and independentlyremovable and replaceable in the event of injury thereto. The dovetailed tongues 18, formed integrally with the segmental blocks at the under side thereof, extend the entire length of the blocks and rest fiat on the outer surface of the basering 17 of the wheel, thereby providing for a firm seating of the blocks in the periphery of the Wheel and insuring the uniform distribu- 'on of strain thereon when clamped by and between the opposite side plates or disks 10. The said segmental blocks 19 of each wheelsection of the cylinder are fitted in position on the wheel with their ends in direct contact to present an unbroken circle or series of said blocks, and thereby leaving no spaces exposed between the ends of the blocks, into which the cotton-seed could possibly work; and it will be further observed at this point that the side edges of the blocks 19 overlap the peripheries of the plates or disks l0, and thereby cover the entire periphery of the wheel, so that no metal parts of the wheel are exposed within the space in the casing in which the delinting operation occurs. In the drawings the outer working faces or surfaces of the abrading-blocks are illustrated as perfeetly plain to present a perfectly regular and cylindrical abrasive surface for the cylinder throughout its entire area; but it will of course be understood that the working faces or surfaces of the blocks may be made of any form desired without departing from the features of construction contemplated by the present invention.

All of the block-holding wheels of the cylinder are constructed alike and are arranged side by side in close contact, so as to leave no spaces between the meeting sides or faces of the wheels, the hub-sleeves 11 of the wheels receiving and being fitted to the cylindershaft 8 so as to revolve therewith. It will be observed that the particular construction of each wheel with the side edges of the blocks 19 flush with the outer surfaces or faces of the plates 10 permits such wheels to be arranged in such close relation as to present a practically solid emery-surface over the en tire exterior area of the cylinder without exposing any vacant spaces or metal parts, all of which is very important for the reasons hereinbefore stated.

At one side the cylindrical casing 53 has fitted thereto one end of an ordinary air-Hume 20 (illustrated in dotted lines in Fig. 1) and which is commonly employed with cottonseed-delinting machines, and in its side next to the said fine 20 the casing 2 is provided with a series of vertically-disposed apertures 21 for receiving therein the outer extremities of the thin steel spikes 22 of a revolving lint-remover 23. The revolving lint-remover 23 essentially comprises, preferably, a light wood body 24, mounted on a revolving shaft 25, having suitable belt connections for operating the same, and spaced circular series of the steel spikes 22, fitted at their inner ends to the body and extending radially therefrom, said spikes being provided with outer obtuseangled ends 24-, adapted to work through the apertures 21 and project sufficiently far within the casing to catch the lint fiber and drag the same through the apertures into the airflume 20, from whence it is removed by atmospheric suction in the usual way. There is a circular series of the thin steel spikes 22 for each aperture 21, and by reason of being light and flexible and spaced apart the said spikes will readily remove the lint fiber from the casing, even when damp, without possibility of being gummed or overheated, as is the case with saws and similar lint-removers. The light body 24 of the lint-remover permits of a very rapid rotation thereof, which is quite necessary to insure the thorough removal of the lint and a consequent obviating of a choking of the machine.

Changes in the form, proportion, and the minor details of construction maybe resorted to Without departing from the principle or sacrificing any of the advantages of this invention.
